The last time we saw Pincus speak earlier this fall, he mentioned that 33 million people had played Zynga games – just the previous day. Assuming that Facebook is still well under 640 million users, it’s pretty clear that more than half of Facebook users have played a Zynga game.

Pincus also discussed how at any one time an average of 4 family or friends of just about everyone on Facebook is playing a Zynga game, which is a pretty amazing statistic too. In the future, Zynga plans to use this to entice others (most likely through push notifications) that their good friends or family are currently playing.
